Re-installation failed due to different application signatures

在導入已經存在的項目時出現的錯誤Re-installation failed due to different application signatures

調試信息如下：
[2011-06-09 10:08:37 - ApiDemos] Re-installation failed due to different application signatures.
[2011-06-09 10:08:37 - ApiDemos] You must perform a full uninstall of the application. WARNING: This will remove the application data!
[2011-06-09 10:08:37 - ApiDemos] Please execute 'adb uninstall com.example.android.apis' in a shell.
[2011-06-09 10:08:37 - ApiDemos] Launch canceled!

在網上查是這樣的：

這時先運行android模擬機，並在cmd內運行,當然你要定位adb.exe的目錄,我是放在E:\Android\android-sdk-windows\platform-tools 下

E:\android\android-sdk-windows\platform-tools> adb uninstall com.example.android.apis.

重新運行就可以了
